You use it just as you would at any of the other mixer locations. That means you need pipe, fuel, concrete, sand, and dirty water to craft concrete base parts. This is from the comfort of your base and not out in the mixer cities where AI etc.. can get you. Hope that helps you a little.
Hello Justin, All recipes are available in game. You can access the recipes by selecting an item, for this example I will use sand. With the sand in your characters inventory double left click the item in inventory. A dialog box will pop up and at the top of that box will be 2 tabs "details" and "Recipes", select the recipes tab. Another window will open showing everything that can be crafted using sand and if you click on the items you want to craft it will tell you specifically what items you need to carry on you to craft the item. Let me know if this helps or if you like I can jump in game next time I see you online and show you.
